Weed ID as much as I can Unidentified alien life form. I've never seen that. Broadleaf even though it's needly Oxalis or black medic. Broadleaf often called clover but it isn't. dandelion thistle dallisgrass If 2x per week mowing is not for you, you might look into St Augustine. It requires much less maintenance. Don't let the cost scare you. If you are patient and don't need an instant change over, you could put in one piece of St Aug in the front on each side of the driveway and a couple pieces in the back, overall cost so far is less than $10.00, then just let those grow out into the bermuda. St Aug spreads at about 10 feet per year when the temps are in the 70s. As the St Augustine spreads, the bermuda will go away. If you want to do your bermuda properly, that requires frequent mowing and monthly doses of fertilizer. St Augustine can go 2 weeks before mowing and only needs fertilizer 3x per year. I can tell by looking at your neighbor's lawns that they're not doing frequent fertilizer and likely are mowing too high, too. Also if you want to keep the HOA away, you should invest in a string trimmer to manicure the edges of your lawn at the concrete. Right now even with a haircut it looks like a bad haircut with the runners trying to escape. I use a battery powered Black & Decker string trimmer. It's perfectly fine and quiet for simple lawn edging. If you are interested in organic fertilizer, you can save a lot of money by using the raw materials that go into organic fertilizers. I like ordinary corn meal and alfalfa pellets. Both are available in plain brown bags at the feed store. Application rate is 15 pounds per 1,000 square feet. After your initial dose you can continue with the same rate or double or triple it without fear of hurting anything. Bermuda can take all the fertilizer you can throw at it. The only glitch with organics is they take a full 3 weeks to see the improvement. So if you're planning a party and the grass is yellowish, fertilize 3 weeks before the party. For your garden plants and veggies, you can put a heaping handful under each plant on a monthly basis.

Another option is Gordon Ornamec 170, it's cheaper than 2 bottles of the Bayer and will last you many years. It's also good for other tough weeds like quackgrass and dallisgrass. https://www.amazon.com/Ornamec-170-Herbicide-32-oz/dp/B008MZQE6O/ref=sr_1_1?ie=UTF8&qid=1470488280&sr=8-1&keywords=ornamec+170 Yes, you will need to apply a pre-emergent. I recommend prodiamine, it will control this and most other weeds.

Many herbicides (e.g. 2,4-D, dicamba, etc.) use auxins, which basically cause the weed to go through an unregulated insane growth spurt. The plant grows so intensely and so quickly that it dies. For this to work, the plant actually needs to be actively growing before the application is made. If you are still in the early stages of spring, with lows that still drop down below the 40s, perhaps the weeds aren't fully awake enough to absorb the treatment?

Is it too late to stop you from sending soil to TAMU? Unless you're a dyed in the wool Aggie, please send it to Logan Labs and get the $25 test (basic). TAMU has a history of problems with their soil test lab...which they admitted to several years ago. Bermuda is not a low maintenance lawn if you want to have one of the best. If you want to have one of the best looking lawns in the hood, then bermuda will be a high intensity workout with 2x per week mowing at the mower's lowest setting and monthly (yes, every 30 days) fertilizer. Texas Weed's instructions were what you need to do to have a very nice lawn. The fertilizer that TW was talking about is the Lesco 44-0-0. It is a urea product. While the chemistry of urea is organic, the product is synthetic and has none of the organic benefits of using something like Milo, alfalfa, or soybean meal. Bermuda loves the heat and it loves fast release fertilizer in the heat. The only thing about the fast release is you have to water it down before dark on the day you apply it. If you get dew on it the next morning it can even burn bermuda. If you decide to use Milo or another organic product, go ahead and use it monthly. While it is slow release, you'll see the benefit in 3 weeks. It will not go away in 3 weeks - that's just when you see the impact. Keeping it going continuously every month is what bermuda needs. When you read stuff on the Interwebs about lawn management, make sure you are reading about bermuda grown in a hot environment. For example you might have been reading about mowing fescue on a website out of New York. Typically websites will tell you about their local situation and not your specific situation. I don't get crabgrass, so I don't have the herbicide experience to really help you. The best crabgrass prevention is dense turf and infrequent watering. Follow the bible. People have written in here to thank the site for helping them get a dense turf that rejects their neighbor's crabgrass lawn from spreading. Do you have crabgrass already as of today? Or are you just anticipating getting it?
